Fire extinguisher types
• There are different types and styles of fire
extinguishers available around campus.
• Know the types, styles, and location of
extinguishers that can be found in your
immediate and surrounding area.
• The proper extinguishing agent will need
to be used to eliminate one of the vital

that are serviced annually by Eastman Fire
Protection and Gallagher Fire Equipment
Co.
Dry Chemical Fire
extinguisher • The dry chemical fire extinguisher is
the most common fire extinguisher found on all of Detroit Mercy’s campuses.
• The extinguisher works by interrupting the chemical chain reaction blocking the Fuel from Oxygen.
• It sprays a very fine powder in an attempt to coat the fuel and smother the fire.
Carbon Dioxide (CO2)
Fire extinguisher • The CO2 fire extinguishers can be
used for fires involving electrical equipment and Class B liquid fires.
• The extinguisher works by displacing oxygen from the fire and replacing it with Carbon Dioxide.
• Due to displacement of Oxygen, do not used in confined areas. Also, it is not recommended for outdoor fires.
• The gas is extremely cold (-40 degrees). If the extinguisher does not have a fixed horn, a glove can be worn while holding the hose.
No fixed Horn
Fixed Horn
Clean Agent Fire
extinguisher • The Clean Agent fire extinguisher is
not commonly used at any of Detroit Mercy’s campuses.
• Detroit Mercy’s clean agent extinguishers is rated for Class B and C fires.
• The clean agent is a liquid that inhibits the chemical reaction.
• It will not damage sensitive and irreplaceable materials, equipment and facilities. It leaves no residue and requires no cleanup after discharge.
K Guard Fire extinguisher • The K Guard fire extinguisher is
found in Kitchens at all of Detroit Mercy’s campuses.
• K Guard fire extinguishers are rated for Class K fires.
• It contains a pressurized liquid agent that inhibits the chemical reaction.
• Please be aware that using this type of fire extinguisher on an oil or grease fire may cause the grease or oil to splatter.
• Keep enough distance between you and the fire.
Appropriate time to use a
fire extinguishers
• Alarm has been sounded. (Check your area for the nearest pull station before an

Method for using
fire extinguishers Hold the extinguisher upright
•PULL the pin
•AIM at the base of the fire
•SQUEEZE the handle
•SWEEP the base of the fire
Do not aim high at the flames
PULL Keep distance between you and the fire.
Ensure you have a safe escape route behind
you. With a firm grip on the handle and the
pin, PULL the pin, breaking the seal and the
pin completely clear of the hole.
AIM Keep distance between you and the fire. Ensure you have a safe escape route behind you. With a firm grip on the handle and the nozzle, aim the nozzle at the base of the fire closest to you.
SQUEEZE Keep distance between you and the fire. Ensure you have a
safe escape route behind you. With a firm grip on the
handle and the nozzle, aim the nozzle at the base of the fire
nearest to you and squeeze the handles together.
SWEEP Keep distance between you and the fire. Ensure you have a
safe escape route behind you. With a firm grip on the
handle and the nozzle, aim the nozzle at the base of the fire
nearest to you and squeeze the handles together. SWEEP
side to side at the base of the fire.
Let’s Review
First priority is your safety.
Secondly, ensure that the building fire
alarm is activated to warn other
occupants.
• If the fire is small and contained, you
know the type of fuel, and have the
appropriate fire extinguisher, you can
attempt to extinguish the fire with
your back toward a safe escape route.
Prevention methods
• Know how to handle and store
chemicals
• Keep work areas clean and clutter-free
• Know about the chemicals you work with
Prevention methods
• Know what you are expected to
do in an emergency
• Become familiar with the
University of Detroit Mercy
